PAVING-BRICK.

I-ECIFXCATION forming part of Letters Patent No. 487,652, dated December6, 1892.

Application filed June 23, 1892.

T0 aZZ whom it may concern:

Be it known that I, LESLIE O. TURLEY, a citizen of the United States,residing at Portsmouth, in the county of Scioto and State of Ohio, haveinvented certain new and useful Improvements in Paving-Bricks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in paving-bricks; and the object isto provide a brick of improved construction which when laid in apavement may not rise above or fall below the level of the remainingbricks composing the pavement, and also to provide means for slightlyseparating the contiguous faces or sides of the bricks in the pavement,

so that sand, cement, grout, tar, or other filling may readily pass downbetween the bricks for the purpose of filling all interstices andrendering the pavement firm and solid.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference are used to denote beingparallel and equal to each other, and

the surfaces being plain, except upon the sides a a, which latter areformed the one with a groove or concavity 13 running the length of thebrick and the other with a corresponding rib or tongue B, so that whenthe bricks are properly placed in the pavement the convex rib of onebrick will fitthe corresponding concavity of the adjacent brick, therebycausing the bricks composing the pavement to mutually support and braceeach other, so as to prevent an individual brick from sinking below orrising above the level of the other bricks in the pavement.

To adapt the bricks to be readily laid in forming the pavement withoutloss of time by reason of a tight fit, the concavities B are Serial No.437,806. (No model.)

preferably made slightly larger than the convex ribs B. In moldingthebricks provision is also made for building up a small line of materialin relief, so as to form a series of projecting ribs or welts D D on oneface thereof, preferably on the same face with the convex rib. Thesewelts may be either straight or curved, but should not be continuous,and are designed to hold the faces of adjoining bricks slightly apart,so as to permit sand, cement, grout, tar, or other suitable filling toreadily pass down between the contiguous faces to the under edges of thebricks.

In Fig. 3, instead of a concavity and corresponding convex rib the brickis formed with a rectangular recess E on one face thereof and acorresponding rectangular rib E of slightlyless size than the recess forthe same purpose as the concave recess and convex rib of Figs. 1 and 2,this latter construction being preferable in many cases as affording amore rigid connection, which causes the bricks to interlock and befirmly bound together, so as to prevent independent vertical movement ofindividual bricks. This brick is also formed with welts D D in reliefupon its face a for the purpose of permitting the filling, as abovedescribed, to pass down between the bricks. It may also be desirable toform the longitudinal rib in sections or provide the same withtransverse grooves or channels to permit the passage of the fillingbelow the rib.

In Fig. 4 the welts D are bowed or curved to more readily permit thepassage of the filling and prevent lodgment thereof upon the welts.These welts may consist of a small line of material in relief upon oneface of the brick only, or upon two or more faces, if desired, and theymay be larger or smaller than shown in the drawings. The bricks areformed of clay in the usual manner by means of suitable molds and aresubsequently burned in a kiln, forming a hard and solid mass of materialwhich is specially adapted for street-paving purposes. It will beobserved that the longitudinal rib and the concavity or groove areplaced upon the medium faces or sides of the brick, which are commonlycalled the Width or depth sides, and not upon either the shortest or thelongest measurements, and that the opposite faces IOC of the bricks areparallel and equal and at right angles to every other face, so that whenplaced in the pavement with break joints, as indicated in Fig. 2, eachbrick has the immediate lateral support of four other bricks in thepavement and has its greatest thickness disposed perpendicularly to thestreet, so as to afford the greatest strength where required. The upperand lower longitudinal edges of the bricks may also be rounded fromone-eighth to three-eighths of an inch, and the brick may be reversed orturned over, so that if from any cause the upper face of a brick isimperfect the perfect face may be presented to the surface.

Instead of welts of the form shown I may print any desired word or wordsor number or numbers upon the face of the brick in relief, for the samepurpose as the welts and may dispense with the longitudinal concavity orrecess and corresponding rib and have all the faces of the brick plain,except the face with the welts thereon, and other forms of bricks thanthe specific form described may be provided with a line of material inthe na ture of a welt in relief, which shall hold the bricks slightlyapart for the purpose stated. It may also be desirable in some cases todispense with the welts, and instead thereof to form small groovesextending either vertically or in a slanting direction from top tobottom on one side of the brick.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. A paving-brick having its top, bottom,

vided with a series of welts in relief upon one or more sides thereofextending longitudinally of the brick,snbstantially as described.

3. A brick for street-paving purposes, having'a longitudinal recessextending the length of the brick on one face thereof and acorresponding interlocking rib on the opposite face and a series ofwelts in relief on one of said faces, substantially as described.

4. A street-pavement comprising a series of reversible rectangularinterlocking bricks, each having upon one side thereof a longitudinalrecess and a corresponding rib on its opposite side engaging the recessof an adjacent brick, together with a series of welts in relief upon oneor more sides of the brick, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

LESLIE C. TURLEY.
